* It's not a major plot point: While they might share ice cream at some point, it's likely a small, casual moment that wouldn't be a significant plot point.
* There are many episodes: Shugo Chara! has 102 episodes, making it difficult to recall every specific interaction.
To find this specific interaction, you would need to:
1. Rewatch the entire series: This is the most reliable way to find the scene.
2. Check fan wikis and resources: Websites like the Shugo Chara! wiki might have episode summaries or character interaction lists that could help.
3. Search online: Search for "Amu and Ikuto ice cream" or similar phrases to see if any fans have discussed this scene.
However, even after searching, it's possible that scene doesn't exist! The anime might have omitted a casual interaction like this or it might never have occurred in the original source material.
